Abstract

Engine vibration is critical toward overall engine performance, engine lifespan and passenger comfort. Engine sound level is critical toward the environment by increasing the noise polution. An experimental investigation on cylinder block vibration of engine, knock intensity and sound level with research octane number (RON) 95, 97 and 100 was carried out on a spark ignition (SI) engine under different engine speeds (1600, 2000, 2400, 2800 and 3200 RPM). The experiment was conducted in a proper experimental setup with all the equipment and materials. Multiple sensors were used in this experiment to obtain the following data such as accelerometer sensor, knock sensor and microphone. This experiment proved that cylinder block vibration and knock intensity with RON 100 had the lowest reading data compare to RON 95 and RON 97. The sound level (Pa) for RON 100 is the highest compared with RON 95 and RON 97 due to this fuel is able to produce more power and this affected the sound level of RON 100. In conclusion, RON 100 is better in every aspect and suitable for car’s engine which are able to draw out all the fuel performance.
